TYPE-CASTING MOLD.

Application filed July 25, 1924. Serial No. 728,058. r

This, invention relates to a slug casting that the body of the letter is being printed.

Ina certain type of such machine,' the slugs are placed in a galley. and fed by gravity into the jaw of a feeding elementthat advances the slug into the plane of the printing bed plate or chase and that also retracts the same. This jaw of the feedingelement takes over the outer margin of the slugs,'thereby shortening the space which can be typed. Further as the slugs as now constructed descend in the galley, they frequently become jammed or out of proper alignment'causing waste in the printed matter and consequent lossof time. I

It is an object of this invention to overcome these defects in the provision of a mold in which slugs can be cast with lateral slots or notches that are adapted for. cooperating with guide ribs in the galley for maintaining the slugs in proper alignment, and that are also adapted for receiving the jaw members of the feeding element of the printing press so that the printing may extend the full lengthof the slug.

The inventon consists of the novel structure and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views:

Figure 1 is a fragmentary elevational view of the mold gear of a linotype machine.

Figure 2 is a sectional view taken upon the line 22 of Figure 1.

Figure 3 is a sectional view upon the line 33 of Figure 1.

Figure 4 is a sectional view upon the line 4-4 of Figure 1.

Figure 5 is a reduced top plan view of the mold gear.

Figure 6 is a top plan view of a cast slug.

As shown on the drawings:

Referring to the drawings the numeral 1 represents the usual mold gear of a linotype posit-ion, the slug is cast and typed.

machine. This gear is provided with a mold 2 in which a slug 14 is cast and typed. The gear is mounted upon a stationary support- 3 and is intermittently rotated by a pinion 1. IVhen the mold 2 is in its upper horizontal The gear then makes a three-quarter turn when it comes to'a dwell'for the ejectment of the slug.

This invention concerns itself with mechanism whereby slots 15' may be cast in the lateral edges of the slug and which operates automatically during. the operation of the machine. The form of mechanism illustrated for carrying out this invention comprises a pair of rectangular reciprocating slot forming elements in the form of rods 4 which are suitably supported and guided upon the gear wheel 1 for entering the ends of the mold 2 as shown in Figures 1 and 2. The outer end of each element 4 is pivotally' connected to the upper slotted end of one arm 5 of a bell crank lever to allow for arcuate movement of the lever." The other arm of each bell crank lever is provided at its end with a roller 7 that lies upon the periphery of a stationary cam 8 secured upon the end of the support 3. Each bell crank lever is providedv with an extension 9 having a terminal aperture for receiving the end of a rod 10 which is pivoted at its other end to the gear wheel 1. A coil spring 11 surrounds each rod 10 and is confined between the extension 9 and an abutment on the pivoted end of the rod 10. In referring to Figure 1, it will be noted that the cam 8has a concentric portion 12 which extends about three-quarters of the circumfere'nce of the cam, the upper portion or quarter of said cam being in the form of a dwell 13. IVhen the rollers 7 are positioned in the dwell, the rods 4 are a short distance in the mold 2, in this position of the parts which is illustrated in Figure 1, the slug is cast and typed in the mold. After the slug is cast, the gear 1 will rotate about three-quarters of a revolution for the ejectment of the cast slug. During this rotation of the gear 1, the rollers 7 'will be brought upon the concentric portion of the cam 8 whereby the bell crank levers are automatically operated for withdrawing the slot forming elements 4 whereby the slugs I are released so that the same may be ejected. After the slug is ejected, the gear 1 will rotate about a quarter turn in the same direction. This will bring the mold 2 into its upper horizontal position as shown in Figure 1, with the rollers 7 in the dwell or depression 13, allowing the springs 11 to operate the bell crank levers for injecting the ends of the slot forming elements 4 into the mold 2 in position for casting another slug.

7 From the foregoing, it will be apparent that during the rotation of the mold gear 1, the slot forming elements are automatically injected into and withdrawn from the mold in timed relation with the other parts of the machine so that the slugs may be formed with slots and ejected from the mold.

I am aware that many changes may be made, and numerous details of construction may be variec through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

1. In a slug casting machine, a rotary member formed with a mold for casting slugs, slot forming elements slidable into and out of the ends of said mold, bell crank levers pivoted upon said member, one arm of each lever being connected to a slot forming element, a stationary cam whereby said elements are withdrawn from said mold, and yielding means for injecting said elements into said mold.

2. In a slug casting -machine, a rotary member having a slug forming mold, slidable slot forming elements carried by said member, a stationary cam and lever mechanism connected to said elements and operable through contact with said cam forwithdrawing said elements from the ends of said mold.

3. In a slug casting machine, a rotary member having a'inold, slot forming ele ments adapted for entering the ends of said mold to cast slots in the slug and means operable during the rotation of said member of controlling said elements.

4;. In a slugforming mold, a pair of slot forming elements adapted for entering the ends of the mold for forming slots in the slugs, and means for automatically withdrawing said elements in order that the slugs may be ejected.

5. In a slug casting machine, the combination with the slug forming mold, of slot forming elements for entering the ends of said mold and mechanism automatically operated during the operation '01 said machine for controlling said slot forming elements with respect to said mold. r

6. In a slug casting machine, the. combination with the slug forming mold, of slot forming elements reciprocable with respect to said mold, and mechanism automatically operated during the operation of said machine for causing said elements to reciprocate into and out of the ends of said mold. V

7. In a slug casting mac-hinath'e combination with the rotary slug forming mold,'of reciprocating slot forming elements carried thereby, yielding means for causing said olements to enter said mold to form slots in the opposite ends of a slug, and meansautomatically operated during the rotation of said mold for retracting said elements.

combination of a mold arranged forcasting type slugs, slides mounted in said mold and arranged to be projected tliereinto'to iorm slots in the ends of the slug, and automatic means for periodically withdrawing said slides to permit the slug to'be ejected from the mold. 1

9. In a machine for casting type slugs,the combination of a mold arranged for casting type slugs, slides mounted insaid mold and arranged to be projected thereinto to form slots in .the slug, and-means for periodically withdrawing said, slides to permit the slug to be ejected from the 'mold, saidmeans including a cam, bell crank levers attached to said slides and arranged for actuation. by

said cam, and yieldable means arranged to urge the slides into the moldand the bell crank levers against the cam.
